Specification of Letters ?atent.

Patented Aug. '8, 19222.

To all wlhom 2 25 may concern:

Be it known that I, EDWARD F. DUDLEY, a citizen of the United States,and resident of Oak Park, in the county of Cook and State of Illinois,have invented certain new and useful Improvements in Printing Presses,of which the following is a specification.

This invention relates to a printing press and more particularly todistributing roll mechanism therefor.

One of the objects of the invention is to make it possible to move thedistributing rolls out of operative association with the inking rollswithout changing the operative relationship between the distributingrolls and their driving and vibrating mechanism.

Another object is to simplify and improve the driving and vibratingmeans for the distributing rolls.

Another object is to provide distributing roll mechanism adapted to meetthe various requirements for successful commercial operation.

Generally speaking these and other objects are accomplished by providingin a printing press, the combination of a distributing roll, means foractuating the same, and means for moving said distributing rolls fromtheir normal operative position without changing the relationshipbetween the distributing roll and the actuating means therefor. 1

The invention is illustrated on the accompanying sheets of drawings inwhich,

Figure 1 is a fragmentary side elevation of a printing press, embodyingmy invention.

Figure 2 is a fragmentary side elevation, taken from the opposite sideof the same printing press, and

Figure 3 is a fragmentary plan view of the same printing press.

The various novel features of my invention will be apparent from thefollowing description and drawings and will be particularly pointed outin the appended claims.

This invention has to do, particularly with ink distributing rolls, thedriving means therefor, the vibrating means therefor, and means wherebythe distributing rolls may be moved away from their normal operativeposition for making accessible the inking rolls and at the same timewithout disturbing the connections between the distributing rolls andtheir driving and vibrating means.

Referring particularly to the figures of the drawings, it will be notedthat I have disclosed my invention in connection with a printing press,including a frame 10, supporting a plurality of inking rolls 11, each ofwhich inking rolls is mounted in suitable bearings 12. Under normaloperating conditions these rolls occupy their lowest ppsition to engagea cooperating surface 13.

owever,.when the machine is not in operation the various parts are soshifted with respect to each other that a spring 14, which isoperatively connected through suitable mechanism to all of said inkrolls, is effective in raising all of said inking rolls away from saidcooperating surface 13, to prevent flat spots being formed.

Mounted in the frame 10, is a shaft 15, carrying at one end thereof, aworm wheel 16, which meshes with a worm 17, formed at one end of asupported shaft 18, carrying an operating crank 19, whereby the shaft 15may be rotated. Secured to the shaft near one end thereof is an oiltight casing 20, in which ink distributing roll shafts 21 and 22 aremounted. This oil tight casing also encloses and carries a gear 23.which is mounted concentrically with respect to the shaft 15 and ismovable independently thereof, an intermediate gear 24 forming thedriving connection between the gears 23 and 25, the latter being mountedupon one end of the distributing roll shaft 21, and another intermediategear 26 operatively connecting the gear 25 and a gear 27 mounted uponone end of the other distributing roll shaft 22. In other words, the oiltight and oil filled casing 20 carries and encloses gears 23, 24, 25 26and 27. Also secured to the shaft 15,

.near its opposite end, is a bracket 28 in which the opposite ends ofshafts 21 and 22 are mounted.

Referring now more particularly to the driving means for the inkdistributing rolls 29 and 30, respectively, mounted upon the shafts 22and 21, it will be noted that a relatively large driving gear 31 isrotatively supported in the frame 10 and meshes with the gear 23, fordriving the train of gears 23 to 27 inclusive. It is to be noted thatthe gear 23 is loosely mounted upon. the shaft 15, which is the shaft towhich the oil tight casing and the arm 28 are secured. This oil tightcasing 20 and arm 28 carry, among other things, the ink distributingrolls 29 and 30, and as a result thereof when the shaf-tl5 is caused torotate by the actuation of the crank 19, the distributing rolls andtheir driving gears, as a unity,

are swung about with the shaft thedesired angle, which in this case isshown to be 90, for making accessible the inking rolls 11. It is notedparticularly that the gears are not in any" manner whatsoever caused tomove out of mesh with each other during theswinging movement of the inkdistributing rolls. In other words, the driving relationship between theink distributin-g rolls and their driving means is not changed in anymanner whatsoever, thereby obviating the disadvantages and troublesoccasioned in attempting to place cooperating gears back into mesh whenthey have been withdrawn therefrom.

In Figures 1 and 2, the ink distributing rol-l's 29 and 30, with theirassociated driv ing gears and supporting casing and bracket ar'eshown intheir normal operative posi- 7 tion in full lines and in adjustedpositlon in dotted lines.

Referring particularly to Figures 2 and 3 of the drawings, the vibratingmeans for the distributing rolls is shown to include an actuatedeccentric 32, to which is connected one end of a link 83, the other endof which is pivotally connected to an arm 34:, secured to a shaft'35, towhich is operatively connected a toothed miter segment v 86, meshingwith 'a miter gear 87, operatively connected to a lever '38 pivotallysupported atits lower end and having at its upper end aforked portion 39having pins 40', extending radially into a groove 41 in a'collar 42,slidably mounted upon one end of the shaft 15. This collar 42 alsohas aci'rcumferentialgroove 6L3 for the reception of a cooperating roller 44,mounted in one end of a lever i5, pivotally mounted intermediate itsends to a vertically arranged shaft 46. "Also secured tothis shaft 46-isan arm 47. On opposite sides of the shaft 46 the distributingroll'shafts'2l and 22 are operatively connected with the'lever l 5yandarm 47, whereby when the lever iscaused to vibrate back and forth thedistributing rolls 29 and 30 are caused to 'vibrate transversely inopposite directions, for distributing ink upon the inking rolls 11,which are arranged in pairs directly below and at either side of thedistributing rolls.

From this arrangement it is apparent that the ink distributing rolls 29and 30 are continuously vibrated back and forth during the actuation ofthe eccentric 32 and 'through the connections hereinabove described, In

this'fconnec'tion it will be noted that the distributing rollswith theirsupporting casing and bracket and driving gears may be raised i ntotheir dotted line'position without changing the operative relationshipbetween the distributing rolls and their vitributing rolls.

may be moved in a manner to render the,

inking rolls accessible without in any manner whatsoever changing theoperative relationship between the distributing rolls and their drivingand vibrating means, at the same time providinga simple and compactarrangement adapted to meet the requirements for successful usage.
